Progress on nanomaterial -based chemical sensors and biosensors

Recently, nanomaterial- based chemical sensors and biosensors have attracted considerable attention due to their excellent sensitivity, high selectivity and long- term stability. Due to the quantum size effect and surface effect of nanomaterials, the characteristics of sensors can be improved obviously when the electrodes are modified with nanostructured materials. Moreover, super high sensitivity and excellent selectivity sensing devices could be designed when nanomaterials are modified with functional groups. In this paper, we mainly focus on demonstration the research on nanomaterial modified chemical and biosensors in our group. In addition, the progress on nanosensors are also described.
